The Flower Essence Society (www.flowersociety.org) funds scientific research studies using strict double-blind placebo protocols.
Dr. Jeffrey Cram, Ph.D. (1949-2005), a former research and clinical psychologist with the Sierra Health Institute in Nevada City, California, completed two double-blind placebo studies of the effects of flower essences on stress.
The first study involves the use of Five-Flower Formula (Dr. Bach's emergency formula, also sold under the brand name Rescue Remedy.) by subjects in an induced stress situation - a mental arithmetic exercise. In the test group of 24 subjects, those using the flower remedy were found to have a significantly reduced level of reactivity, as measured by muscular activity (EMG) at spinal locations corresponding to the heart and throat chakras.
